Quang Ninh Province, situated in Northeast coast of Vietnam, has about 250km of shoreline, many estuaries, and tidal flats and over 2000 islands. The diversified nature, natural landscapes and ecosystems grant the province a great potential for tourism and specially seafood products. Peanut-worms (Sipunculus nudus) are exploited and used as popular seafood in international and domestic markets as special food of high nutritional and pharmaceutical value.
This book is written with the objective of providing fundamental knowledge
concerning the biological and health effects of environmental pollutants on
living systems. The book emphasizes the chemical and biological characteristics
of major pollutants found in our environment and their impacts on the health
of living organisms, including not only humans and animals but also plants.
How are pollutants transformed after their release into the environment? How are organisms exposed, and how do physiological alterations impact population dynamics and community structure? What direct or indirect impacts occur? As early as the 50s and 60s people living near industrial plants began to recognize undesirable changes in their environment - and to ask these very questions. The discipline of environmental toxicology addresses these questions.
This paper presents the results of soil characteristics study and orientation for rational and sustainable use of major soil types in Thai Thuy District, Thai Binh Province, where is facing many environmental problems. The interactive process between river, sea and human activities over time has resulted in the characteristics of 10 soil types, which are grouped in 4 main classes (acid sulfate soil, saline soil, alluvial soil and sandy soil). They have been used for agricultural production (mainly for rice and other crops growing).
The objectives of this chapter are to: Discuss the prevalence of timber theft, explain agrichemical theft, discuss cattle and horse rustling, outline several methods of horse and cattle identification, summarize measures to prevent rural and agricultural crimes, distinguish between situational and professional poachers, understand investigative techniques used in wildlife crimes, list and describe the characteristics of hazardous waste, discuss methods of investigating environmental crimes.
Earth's ecosystems continue to exist because they are sustainable. Two fundamental characteristics are crucial to sustainability. First, ecosystems' energy source, the Sun, is non-depletable and non-polluting. Second, there is efficient recycling of nutrients and other chemicals through organisms and through geological and chemical processes that result in no waste accumulation in ecosystems. This chapter provide knowledge of ecosystems: How they work.
Some main geographical
characteristics of Vietnam:
-Vietnam extends more than 1,650
km from north to south, it’s altitude
varies from sea level to a maximum
of 3,143 m.
-Three quarter of Vietnam is hilly
or mountainous. Forest cover is
about 12.3 million ha (over 37 % of
the total land area of the country).

Why do some contaminants remain in soils indefinitely? How much of a threat do they pose to human health or the environment? The need for effective and economic site decontamination arises daily. Geoenvironmental Engineering: Contaminated Soils, Pollutant Fate, and Mitigation discusses why soils remain contaminated, focusing on the development of the factors, properties, characteristics, and parameters of soils and individual contaminants.

This success story has been accompanied by growing concern over the environmental impact and
sustainability of the industry. This has mainly been based around the localised impact upon the
production sites, concern over the impact upon wild salmon and sea trout stocks as well as wider
ecosystem effects. One of the factors considered in the latter category is the need for considerable
volumes of fish meal and fish oil in carnivorous fin fish diets.
The mushroom is the fruiting body of the macrofungi. Approximately 14,000 described species of
fungi produce fruiting bodies that are large enough to be considered mushrooms using our definition,
which states that “the mushroom is a macrofungus with a distinctive fruiting body that can be either
epigeous (aboveground) or hypogeous (underground) and large enough to be seen with the naked
eye and to be picked by hand.” According to this definition, in contrast to other definitions,
mushrooms can be Ascomycetes, grow underground, have a nonfleshy texture, and need not be
In 2001 I was contacted by a consortium of research institutions and wind energy
interests with a request to provide some background information on the operational
characteristics of acoustic radars or SODARs. The consortium partners had set
up and been funded for an European EU project to evaluate SODARs as a tool in
monitoring wind flows at wind turbine sites. They felt reasonably confident in their
knowledge of SODARs and had purchased some instruments, but wanted to be able
to consult on any more complex issues which arose.
The environmental challenges we face today include all of the same ones
that we faced more than 30 years ago at the first Earth Day celebration in 1970.
In spite of the unflagging efforts of environmental professionals (and others),
environmental problems remain. Many large metropolitan areas continue to be
plagued by smog, beaches are periodically polluted by oil spills, and many running
waters (rivers and streams) still suffer the effects of poorly treated sewage
and industrial discharges....
The purpose of the
CRC Handbook of Engineering Tables
is to provide in a single volume a ready reference
for the practicing engineer in industry, government, and academia. The tables and figures provided in
this book include data and information from all fields of engineering in a comprehensive format. This
information is organized into five sections: Electrical and Computer Engineering; Civil and Environmental
Engineering; Chemical Engineering, Chemistry and Material Science; Mechanical Engineering; and
General Engineering and Mathematics.
As discussed in Section I, no prior study examines the relation between
corporate governance mechanisms and the likelihood of an earnings restatement.
A few studies examine the consequences of earnings restatements.
William Kinney and Linda McDaniel analyze the stock price reaction for a
sample of 73 firms that restated earnings between 1976 and 1985.18 They
find that, on average, stock returns are negative between issuance of erroneous
quarterly statements and its corrections.
This report uses a new methodology for profiling sectors, building a picture of the LCEGS sector from
the bottom up, rather than from the top down as is traditionally the case.

The expert interviews served as a complement to the information from the literature review and the
questionnaire, about the overview and application of financing mechanisms. In general, the
interviews focused on identifying types and examples of innovative financing mechanisms.
Wireless sensor networks promise an unprecedented fine-grained interface
between the virtual and physical worlds. They are one of the most rapidly developing
new information technologies, with applications in a wide range of fields
including industrial process control, security and surveillance, environmental
sensing, and structural health monitoring. This book is motivated by the urgent
need to provide a comprehensive and organized survey of the field.
Plants are a distinct kingdom of organisms that possess unique properties of
reproduction, development, physiology, and adaptation. Plant diversity refers to the
variety of plants that exist on the Earth. Plants, in order to survive, have to compete
with other plants and organisms in an ecosystem. Over time, they have developed
various characteristics to help them survive, which leads to plant diversity.
The Baltic Sea is one of the most investigated water bodies in the world. For
decades, the many highly industrialised nations around the Baltic have financed
basic and applied investigations, as well as the building and development of
research stations and vessels.
After World War II, research in the Baltic Proper was intensified and investigations
became much more international. The main goals of such investigations were
analysis of the eutrophication and pollution of the Baltic Sea, and development of
mitigating strategies (e.g. the HELCOM-Program).
